CVE-2012-0861
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe vds_installer in Red Hat Enterprise Virtualization Manager (RHEV-M) before 3.1, when adding a host, uses the -k curl parameter when downloading deployUtil.py and vds_bootstrap.py, which prevents SSL certificates from being validated and allows remote attackers to execute arbitrary Python code via a man-in-the-middle attack.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe vds_installer in Red Hat Enterprise Virtualization Manager before version 3.1 uses curl with the -k flag when downloading deployUtil.py and vds_bootstrap.py during host addition. The -k parameter disables SSL certificate validation, allowing a man-in-the-middle attacker to intercept the connection and inject arbitrary Python code for remote execution.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the installed Red Hat Enterprise Virtualization Manager versionRun: rpm -q rhevm or check the /etc/redhat-release file for the RHEV version. Alternatively, use the management portal to view the system version.Affected if The version is 3.0 or earlier, specifically 2.1, 2.2, 2.2.3, or any 2.x/3.0.x version.
-
Verify the vds_installer component is presentCheck for the vds_installer package: rpm -q vds_installer or search for the binary in /usr/share/rhev-vds-installer/ or similar paths.Affected if The vds_installer package or its binaries are found on the system.
-
Examine curl usage in host addition processDuring a test host addition or by inspecting the vds_installer scripts/logs, look for curl commands containing the -k or --insecure flag being used to download deployUtil.py or vds_bootstrap.py.Affected if The -k flag is present in curl commands fetching these Python files during host deployment.
-
Inspect SSL certificate validation configurationReview the vds_installer configuration files for SSL verification settings. Check if CA certificate validation is properly configured or disabled.Affected if SSL certificate validation is disabled or not enforced for the host addition download process.
A system is affected if it runs Red Hat Enterprise Virtualization Manager version 3.0 or earlier (2.1, 2.2, 2.2.3, or any 2.x/3.0.x) and the vds_installer uses curl with the -k flag during host addition, allowing unvalidated downloads of bootstrap scripts.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataRemove the -k curl parameter and implement proper SSL certificate validation in the vds_installer. Upgrade to RHEL Virtualization Manager 3.1 or later which contains the patched version.
